CULTIVATOR.

Specification of Letters Patent.

Patented Aug. 22, 1905.

Application filed May 24, 1905. Serial No. 262,006.

To all whom, it 772/6117] concern:

Beit known that we, GI-rARLEs E.A. SrIcxnL and HENRY C. ROGERS, citizens of the United States, and residents of Battlecreek, in the county of Ida and State of Iowa, have invented a new and useful Improvement in Cultivators, of which the following is a full, clear, and exact description.

Our invention relates particularly to the construction of disk-cultivator.

The purpose of the invention is to provide a disk-cultivator constructed in two sections so connected that they have independent action and when in action a rocking movement, so that when one section moves upward the other section generally moves downward, whereby the cultivator is not liable to clog or choke in damp and trashy soil.

Another purpose of the invention is to provide ameans for placing the sections in longitudinal alinement or at angles to each other,

as may be required, and to provide an implement which will be light of draft and of weight, strong, durable, and economic in construetion and which will leave the soil in an even condition, well turned over, and with the grain or trash thoroughly covered.

A further purpose of the invention is to provide each section with two rows of disks, one row in front of the other, the disks of one row being in staggered relation to the disks in front or at the rear.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

consists of a top plate 10, which is provided with a longitudinal slot 11, centrally located, and hangers 12 are secured to the under face of the top plate 10, one near each end. Each hanger at its lower end is provided with a bearing-box constructed in two sections 13 and 13, the section 13 being an integral portion of a hanger and said section 1.3 bolted or otherwise removably secured to the section 13. These boxes or bearings are at the front and at the rear of each of the hangers and receive parallel shafts 14 and 15,-as is shown in Figs. 1 and 2. Between the hangers 12 a bracket 17 is located, which is provided at the front and rear of its under portion with bearings 18, as is shown in Fig. 2, likewise constructed in two sections, one removable from the other, and the shafts 14 and 15 likewise pass through the bearings 16 of the said bracket.

Upwardly and forwardly extending elon' gated loops 19 are carried from the forward lower portions of the bracket 17, and at the top or central portion of the bracket a bearing 20 is formed, likewise made in two sections, and in this bearing a ball-socket 21 is produced, as is best shown in Fig. 3. Disk cutters O are mounted to turn on the-shafts 14 and 15, and preferably these cutters are curved outwardly at their peripheries, as shown in the drawings. Said disks C are separated by spacing-sleeves 16, located on the said shafts 14 and 15.

lVhile the shafts 14 and 15 are parallel, the forward shaft 14 is preferably made to extend beyond the inner end of the rear shaft 15, and the outer end of the rear shaft 15 extends be yond the corresponding end of the forward shaft 14, as is clearly shown in Figs. 1 and 3.

Two frames, such as has been described, are connected by a bar 22, having crank-arms 23 at its ends, which terminate in balls 24, fitting in the sockets 21 of the brackets 17 as is shown in Fig. 3. Under this form of connection it is evident that each frame is independent in its action. Either of them may be carried upward and the other downward. Both of them may remain on a level or both may be elevated or have substantially the same inclination. Furthermore, it will be observed that each frame has semirotary movement relative to the connecting-bar 22.

forward portions of the brackets 17 The said draft-rod 27 is carried forward and is loosely bent through a keeper 28, extending from the under face of the said pole 26.

Loops extend from the forwardlower edges of the inner hangers 12 of the frame-sections A and B, and ordinarily a rod 30 has a loose connection at its ends with the said loops 29,

and said rod is bent so as to have two members, one at an angle to the other. Where the members connect, an eye is formed, which eye provides means for the attachment of the said rod to the lower end of a lever 31, which lever extends up through the pole 26 and is pivoted on the said pole, the lever being pro- Vided with the customary thumb-latch 32, adapted to engage with a rack 33. By carrying the lever 31 forwardly through the medium of the rods 30 the two frame-sections A ahd B are placed at an angle to one another, their inner ends being carried rearward and their outer ends forward, as is shown by dotted lines in Fig. 1, and the said frame-sections at any time may be brought into longitudinal alinement, as shown by positive lines in Fig. 1, by throwing the said lever 31 rearward. In arranging the disk cutters C on the shafts 14 and 15 the disks on one shaft are placed in staggered relation to the disks on the other shaft or frame.

A cultivator constructed as above described adapts itself to any condition of ground, turns the earth over in good form, and thoroughly covers the ground. The draft is even, as there is but little swaying of the tongue, and owing to the rocking motion of the frame-sections the drivers seat is rendered more comfortable than ordinary. Furthermore, the implement is constructed as light as possible consistent with strength and all parts are readily accessible for repairs.

Owing to the bearings on the standards 12 and the brackets 17 being made separable, it is evident that the implement may be readily taken apart and repaired and new parts substituted for those which have become worn.

The drivers seat 34 is supported in any approved manner upon the pole. We desire it to be understood that links can be substituted for the form of shifting bar 30 shown in the drawings.

Having thus described our invention, w claim as new and desire to secure by Letters Patent 1. In cultivators, independent frames, parallel rows of disk cutters in staggered arrangement carried by the frames, a draft device, a connecting-bar having universal pivotal connection at its ends with the frames, which bar extends transversely of the machine and has guided movement on the draft device, controlling connections between the frame and the draft device, and means for shifting the positions of the frames.

2. In cultivators, independent frames, parallel shafts carried by the frames, disk cutters mounted on said shafts, the disks on a frame being in staggered arrangement, a connectingbar having a universal-joint connection with the frames, a pole provided with a socket through which said bar loosely passes, and aparallel shafts, the forward shaft at its inner end extending beyond the corresponding end of the rear shaft and the rear shaft at its outer end extending beyond the corresponding-end of the forward shaft, and disks mounted on the said'shafts, the disks on one shaft of a frame being in staggered arrangement relative to the disks on the other shaft of the same frame.

1. In cultivators, independent frames, a rear shaft for each frame, standards forming a portion ofthe said frame and provided with sectional bearings to receive the said shafts, disk cutters located on thesaid shafts in staggered arrangement, a bracket for each frame, through which the said shafts pass, each bracket being provided with an upper hearing constructed in sections, said latter bearings being provided with ball-sockets, a pole, a connecting-bar having sliding connection with the said pole, the ends of which connectingbar terminate in balls, which balls are located in the ball-sockets of the upper bearings on said brackets, and a draft-rod connected with the forward shafts of the frames, the said draft-rod having sliding connection with the said pole.

5. In cultivators, a pole, an independent frame at each side of the pole, parallel shafts carried by each frame, disk cutters mounted on saidshafts, brackets carried by the shafts of the frames, being provided with bearings at their upper ends, a connecting-bar having sliding relation to the pole, the ends of which connecting-bar are mounted to turn in said bearings of said brackets, a draft-rod connected at its ends to the forward shafts of the frames and having sliding connection with the pole between its ends, a lever fulcrumed upon the said pole, a locking device for the lever, and link connections between the said lever and the forward shafts of the frames near the inner ends of said shafts, for the purpose described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
